Class IV: High power lasers (CW: 500 mW, pulsed: 10 J/cm2 or the diffuse reflection limit) are hazardous to view under any condition (directly or diffusely scattered) and are a potential fire hazard and a skin hazard. Significant controls are required of Class IV laser facilities.

Monitor ghosting or screen ghosting, as the name indicates, is a monitor/display issue. It has little to do with your system. Monitor ghosting usually occurs when there are multiple images moving fast on your screen, or when you’re moving your mouse quickly. If your monitor is ghosting on your game, you’ll likely notice:

Simply put, screen refresh rate refers to how often your screen displays a new image. For example, a 60Hz refresh rate means that the monitor refreshes itself 60 times per second.

Lasers and laser systems are divided into four major classifications according to their potential to cause biological damage to the eye or skin. The purpose of these classifications is to warn users of the hazards associated with the laser relative to the Accessible Emission Limits (AEL). These limits are based on laser output energy or power, radiation wavelengths, exposure duration, and cross-sectional area of the laser beam at the point of interest.

Class 2M: Low power lasers (CW: up to 1mW) in visible wavelength range (400-700nm). Class 2M lasers are not hazardous under normal operating conditions because of the aversion reaction. Class 2M lasers may be hazardous if viewed with the aid of optical instruments.

NOTE: There are different logotype labeling requirements for Class IIIA lasers with a beam irradiance that does not exceed 2.5 mW/cm2 (Caution logotype) and those where the beam irradiance does exceed 2.5 mW/cm2 (Danger logotype).

In addition to response time and refresh rate, you could experiment with other display settings to see if it helps solve the monitor ghosting issue. Make sure to test your monitor’s functionality while adjusting. To make additional tweaks, look for these settings:

To test if your monitor has the ghosting issue, you can find several tests online. The most popular tool is UFO Test. You’ll get a green signal saying READY if your monitor doesn’t have a ghosting issue. Otherwise, you may get an orange signal suggesting a specific problem with your monitor.

You may now wonder, why is your monitor ghosting? Ghosting is most frequently seen in LCD monitors, but for any type of monitor, the two main factors remain the same: refresh rate and response time.

Restart your PC for the new driver to take effect. Check if the monitor ghosting issue has gone. If this doesn’t work in your case, try the last solution.

First, you want to make sure that your monitor cable is firmly plugged in. Try unplugging then replugging in the cable and test if the issue persists.

If you’ve identified the issue, check out the fixes below. You don’t have to try them all, just work your way down until you find the one that does the trick!

Automatic driver update – If you don’t have the time, patience, or computer skills to update your driver manually, you can, instead, do it automatically with Driver Easy. Driver Easy will automatically recognize your system and find the correct driver for your exact video card and your Windows version, then it will download and install them correctly:

Class1Mlaser

Class 3R: Moderate power lasers (CW: up to 5mW) for visible wavelengths (400 to 700nm). Up to a factor of five over maximum allowable exposure of Class 2 lasers for other wavelengths. Class 3R lasers are considered low-risk but potentially hazardous.

Although we explained earlier that screen ghosting is primarily an issue of the monitor, not of GPU, you could still try updating your graphics driver. When you can’t identify what’s causing your monitor to ghost, it’s a good idea to do so since it generally fixes and prevents many display issues, which may include monitor ghosting in your case.

Class II: Low-power visible lasers that emit above Class I levels but at a radiant power not above 1 mW. The concept is that the human aversion reaction to bright light will protect a person. Only limited controls are specified.

Class 3B: Moderate power lasers (CW: up to 500mW, Pulsed up to 30mJ) in wavelength range of 300nm to far infrared. Direct eye exposure to Class 3B lasers is hazardous; however, diffusely scattered radiation is generally safe. Direct exposure to skin is a potential hazard.

Class 2: Low power lasers (CW: up to 1mW) in visible wavelength range (400-700nm). The aversion response will protect the eye from damage due to direct exposure. There is no hazard from exposure to diffuse radiation.

If the video port of your monitor is faulty, it could probably cause you screen to ghost. We recommend taking your monitor to a local repair store since it’s very difficult to identify the problematic component and replace it. If your monitor is still under warranty, you may also contact the manufacturer for support.

Class I: cannot emit laser radiation at known hazard levels (typically continuous wave: CW 0.4 µW at visible wavelengths). Users of Class I laser products are generally exempt from radiation hazard controls during operation and maintenance (but not necessarily during service).

Class 1M: Class 1M lasers are not capable of producing hazardous exposure under normal operating conditions, but may be hazardous if viewed with the aid of optical instruments.

Class 2m laserpointer

Class I.A.: A special designation that is based upon a 1000-second exposure and applies only to lasers that are “not intended for viewing” such as a supermarket laser scanner. The upper power limit of Class I.A. is 4.0 mW. The emission from a Class I.A. laser is defined such that the emission does not exceed the Class I limit for an emission duration of 1000 seconds.

Class IIIB: Moderate power lasers (CW: 5-500 mW, pulsed: 10 J/cm2 or the diffuse reflection limit, whichever is lower). In general Class IIIB lasers will not be a fire hazard, nor are they generally capable of producing a hazardous diffuse reflection. Specific controls are recommended.

The good news is, it’s easy to identify if your monitor has this issue. Plus there are some known effective fixes. In this article, we’ll explain what monitor ghosting is, why it happens and most importantly, we’ll cover how to fix it. Read on for more information…

Class 1: Class 1 lasers are safe under all operating conditions. There is no risk to eyes or skin. Class 1 lasers may consist of a higher power laser housed within an enclosure.

You may also want to check if your monitor cable is intact. A damaged monitor cable could result in monitor ghosting, in which case you should change your monitor cable and test if the problem persists.

Sometimes other devices connected to your PC, such as your keyboard or speaker could interfere with your monitor’s function. It could be an issue of proximity, meaning that you just need to keep your monitor far from those devices.

Class IIIA: Intermediate power lasers (CW: 1-5 mW). Only hazardous for intra-beam viewing. Some limited controls are usually recommended.

Response time, on the other hand, is the time it takes for a pixel to shift between colors. The more responsive your monitor is, the shorter the response time it’ll have.

Since lasers are not classified on beam access during service, most Class I industrial lasers will consist of a higher class (high power) laser enclosed in a properly interlocked and labeled protective enclosure. In some cases, the enclosure may be a room (walk-in protective housing) which requires a means to prevent operation when operators are inside the room.

Monitor Ghosting is a common issue that you might see on any monitor. If you’re playing a shooter or an action game, you’re likely to encounter this issue which can ruin the whole gaming experience. It could also occur when you’re editing videos or working on tasks that involve displaying fast-paced scenes.

Or, you could disconnect those devices one at a time and test if your screen still ghosts. Make sure to check the wireless devices as well. If one of your devices seems to cause the ghosting issue, try not to use it with your monitor at the same time.

One way to keep your video card driver up-to-date is to manually update it via Device Manager. If Windows suggests your driver is up-to-date, you can still check if there’s a newer version and update it in Device Manager. Go to the manufacturer’s website, and search for the latest correct driver. Be sure to only choose a driver that is compatible with your Windows version.

Class 4: High power lasers (CW: above 500mW). Direct and diffusely scattered radiation from Class 4 lasers is hazardous to the eye. Direct exposure of Class 4 lasers are also a potential skin hazard and fire hazard.

If your monitor supports variable refresh rates, you can set it to a higher value to tackle the monitor ghosting problem. To view the refresh rate of your monitor and make adjustments if possible:

Accessible Emission Limits (AEL) – the maximum accessible level of laser radiation permitted within a particular laser class. Aversion Response – Blinking of the eye, or movement of the head to avoid exposure to a bright light. Continuous Wave (CW) – Continuous emission of radiation as opposed to short bursts. Controlled Area – An area where the occupancy and activity of those within is subject to control and supervision for the purpose of protection from radiation hazards. Diffuse Reflection – Change of the spatial distribution of a laser beam when it is reflected in multiple directions by a rough or matte surface. Intrabeam Viewing – Exposing the eye to all or part of a laser beam. Maximum Permissible Exposure (MPE) – The level of laser radiation to which a person may be exposed without hazardous effect or adverse biological changes in the eye or skin. Nominal Hazard Zone (NHZ) – The space within which the level of the direct, reflected, or scattered radiation during normal operation exceeds the applicable MPE. Specular Reflection – A mirror-like reflection of a laser beam.

As we mentioned above, refresh rate and response time are the main factors that are responsible for the ghosting issue. You can adjust your monitor’s settings to achieve a higher refresh rate and a lower response time which helps prevent your screen from ghosting.
